wireless-internetMy hubby is looking for a new laptop and he’s quite taken with the new wireless technology. As soon as I hear “wireless”, I think, “radiation?” So I decided to do some research on this. I asked the salesperson at the computer store (and we all know how honest they are) what the electromagnetic radiation was like from a wireless computer. He assured me that computers, unlike cell phones, used radio waves. So it was exactly the same amount of radiation as having as radio playing on your desk, and perfectly safe.

Hmmm….that just didn’t intuitively make sense to me.

So I hit the Internet for further research, and here’s what I dug up. Now, if you like to see original research, you can read this next part and click on the links. But if you just want the end results, then scroll down to the end section titled: CONCLUSION.


You can go here to NASA’s site to get an easily understood definition of exactly what electromagnetic radiation is, and the distinction between the different types of waves: http://imagine.gsfc.nasa.gov/docs/science/know_l1/emspectrum.html

This article tell you what wavelength/freqency wireless computer devices work with (frequency and wavelength are inter-related as explained in the NASA article): http://www.webopedia.com/TERM/W/Wi_Fi.html

Once we know the frequency wireless (WiFi) technology uses, we can then compare that to Radios and TVs.

FM Radio is in the 88 – 110MHz range
Analogue TV (what most people have in their homes) is at 400 – 600MHz
Digital TV is at 600 – 1000MHz.

If you go to: http://www.webopedia.com/TERM/R/RF.html

They give a great definition of radio frequency and then an excellent chart showing the strength of the various frequencies:

“Radio frequency is also abbreviated as rf or r.f. – any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation.”

“These frequencies make up part of the electromagnetic radiation spectrum:
– Ultra-low frequency (ULF) — 0-3 Hz
– Extremely low frequency (ELF) — 3 Hz – 3 kHz
– Very low frequency (VLF) — 3kHz – 30 kHz
– Low frequency (LF) — 30 kHz – 300 kHz
– Medium frequency (MF) — 300 kHz – 3 MHz
– High frequency (HF) — 3MHz – 30 MHz
– Very high frequency (VHF) — 30 MHz – 300 MHz
– Ultra-high frequency (UHF)– 300MHz – 3 GHz
– Super high frequency (SHF) — 3GHz – 30 GHz
– Extremely high frequency (EHF) — 30GHz – 300 GHz”



So, based on the information gathered above, here’s where each item (cell phones, radio, TV, wireless computers) lies in terms of intensity of electromagnetic radiation:

FM Radio is 88-110 MHz –> Very high frequency electromagnetic radiation

Cell phones used to be 824-869 MHz –> Ultra-high frequency electromagnetic radiation. But they can now go up to 3 or 4 GHz.

Wireless computers/internet are 2.4 GHz –> Ultra-high frequency electromagnetic radiation (but nearly up into Super High frequency range).

Therefore, surprise-surprise, wireless computers and their networks are NOT SAFE for frequent, ongoing human use!

Worrying also is regular TV transmission at 400-600 MHz (Ultra-high frequency) and the Digital TV in the 600-1000MHz range (also Ultra-high frequency). But at least one tends to sit a good distance away from a TV! Those of you that already have my new, revised, expanded LISTEN TO YOUR GUT book/program, will know exactly why and how cell phone radiation damages your health – I have an entire section in the book about it with research from prestigious sources like The Lancet (British medical journal). Therefore, we already know how damaging radiation in the Ultra-High frequency range is.

Now, granted, a computer is not pressed up right against your head, or in your pocket like a cell phone is. But once you know the serious damage that cell phones can cause (at the cellular level – no pun intended!), you know that there’s no way sitting a couple of feet away from a similar frequency of electromagnetic radiation for hours at a time is going to be good for your body.

WiFi technology has now been around and used for long enough that there is now solid research on the damage it causes to the body.

There is now plenty of information published on the damaging effects of cell phones, WiFi and other wireless devices – over 2,000 scientific, peer reviewed studies! Many governments in Europe have warned against cell phone and wireless usage – particularly for children, the elderly, or immune suppressed people. There is even research showing that this harmful spectrum of electromagnetic radiation can cause IBS.

So if your health is already an issue (and especially with children), this is just one more stressor you should avoid.

Oh yes, and don’t forget to get rid of your cordless phone – these also operate on the same frequency and are actually more damaging than cell phones since they are continually radiating at high levels.

Needless to say, after seeing these results, our house remains filled with just normal computer radiation from plug-in laptops! Also, keep the radiation issue in mind if you’re thinking about buying a new computer with a really big, high-definition screen – in this case, bigger is not better.



I had my Apple iMac 8.1 with a 17″ glass LED screen tested for EMR and by the time you get about 18″ away from it, there is almost none. I then put a plant next to it to further defray the radiation. So if you are electrosensitive orĀ  protective of your health – then this is a good computer to get. My new Apple iMac 21.5″ also tests out very safely.

My healing program, LISTEN TO YOUR GUT has an entire chapter on eliminating unnecessary toxins (like electromagnetic radiation) from your everyday life. I take you through your kitchen, bedroom, living room, etc. step-by-step and tell you exactly what is harming your health and what you can do about it. Making the changes is EASY as I also provide you with step-by-step instructions and checklists in the Workbook that comes with the program.

You need to use your energy and healing resources for healing yourself – don’t let it be drained away by fighting easily eliminated toxins. Create an environment that supports your healing process, not undermines it.

Is Wireless Technology Safe?

  • Radiation does come from Radio frequencies. The information on your page is misleading and in some cases just wrong. The frequency has nothing to do with the amount of radiation that is emitted. Its the RF wattage! Cell Phones are permitted to operate at higher wattage than unlicensed WiFi and cordless phones.

  • Relay? I am a kid and i have bean surrounded by WiFi since i was 4 years old. Right now i am 13 and i am ok. I think by now i would have a problem like cancer but i do not. I am surrounded by WiFi every minute of every day and i am ok. I do not think that WiFi and cell phones are bad for health i think that they are good because if you are in a emergency and need help and you have your cell phone in your pocket you can call fore help. and if you have WiFi you do not have to be teatherd down on a desk all day. And in a year or two i am getting a i phone :}

  • Hi,

    I signed up for a body building plan which requires the wearing of a Body Bugg.
    I am concerned about EMGs from product, but can’t find anything online that addresses this. Can you tell me anything about the risks.

    Thank you very much.

  • I really admire your confidence; is there any area of natural science that you don’t feel able make proclamations on after 15 minutes of googling? I could really do with some advice on whether I should be worried about recent CERN discovery that neutrinos may be able to travel faster than the speed of light-perhaps you could read a couple of random articles from the web and settle the issue for us?

  • Jeremy – cell phones, WiFi and cordless phones all emit RF microwave radiation. Many cordless phones emit higher radiation than a cell phone – see my blog post on Radiation Testing for laptops and cordless phones.

    Harrison – then why are the fertility clinics telling men not to keep cell phones in their pockets or place their laptop computers on their lap? Even bestselling author Tim Ferriss figured this out – read his book “The 4-Hour Body” for his story.

    Robert – I know nothing about this device – sorry. Try to contact the manufacturer to get the specs on it, then at least you’ll know what you’re dealing with.

    Krisian – To be honest, I’ve spent the last 2 years reading dozens of reports, research papers, etc. on this topic and I still don’t feel I have a handle on how all this technology works, nor how it all works together. I know a guy who installs WiFi networks (and fixes them) and he can’t even answer all my questions. That’s part of what’s so frustrating about trying to figure out what the actual risks are and what the long-term effects are likely to be, and under what conditions. Anyway, your comment made me laugh, so thanks for that – I always appreciate sarcasm done well and yours was top notch!

  • Thank you, Jini! I am particularly excited because YOU did all the research I was going to start doing today. My almost 10 year old was hoping to get an IPod, or an IPod Touch. We decided to wait and get more educated and here, we’re ready to go for an MP3 player instead! We are grateful!

  • LUMINA – you could still get him the iPod Touch and disable the WiFi components – you have to turn off: WiFi, Network, Bluetooth, Location… I think that’s it. Just scroll through every item in SETTINGS and disable anything related to WiFi activities. It’s great that a lot of these devices enable you to turn the WiFi component off – and then you can use the USB cable to download stuff from the internet (games, apps, music, etc.).

  • Your post here is very misleading WiFi is the most “Green” and safe technology of all the wireless technologies cause it uses very little powet only 100mW, its part of the NON- ionizing part of the spectrum and the safe distance for WiFi is only 10cm.

    Taking to a Cell phone that uses 1W of power is far more harmfull as is talking to wireless Dect phones. Also using Microwave oven is more harmfull.

    A CellPhone Tower uses 10 to 40 Watts
    A TV/Radio Tower uses something like 40kW

    So if you throw away your Oven, your tv ,your Cellphone, and the Dect phones in your house then you could worry about WiFi.

    I could do a longer report on this if you would like
